Good point. I just realized that there are two senders on this car, one for the dash gauge (which appears to be working) and another one for the ECU. Perhaps that one is not working! That would give the 'open loop' diagnosis some merit.
Probably it is easier to just replace it rather than try to diagnose.
If I had access to socket 3 codes it might show up. Nothing showing yet on Socket 8 (where code 2 is temp sensor).
Thanks for the suggestion.
